Reusing water from sinks, showers, or laundry (greywater) can help your garden — but not all greywater is safe.
Safe greywater:
- Water from baths, showers, and washing hands
- Minimal soap, preferably biodegradable
- Cool or lukewarm water
Harmful greywater:
- Water with harsh chemicals, bleach, or fabric softeners
- Dishwater with grease or detergents
- Water from toilets (blackwater)
Small-system setup tip:
- Direct greywater through a simple filter into a small submersible tank
- Use a pipe outlet to water a contained garden area
- Rotate where water is applied to avoid salt build-up
- Use immediately or store briefly; don’t keep greywater long
